--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:c17206709f94331e81443e2bdcf135a6ab7428ce commit r12-8533-gc17206709f94331e81443e2bdcf135a6ab7428ce Author: Jason Merrill <ja...@redhat.com> Date: Thu Jun 23 23:14:35 2022 -0400 c++: dependent generic lambda template-id [PR106024] We were wrongly looking up the generic lambda op() in a dependent scope, and then trying to look up its instantiation at substitution time, but lambdas aren't instantiated, so we crashed. The fix is to not look into dependent class scopes. But this created trouble with wrongly trying to use a template from the enclosing scope when we aren't actually looking at a template-argument-list, in template/lookup18.C, so let's avoid that. PR c++/106024 gcc/cp/ChangeLog: * parser.cc (missing_template_diag): Factor out... (cp_parser_id_expression): ...from here. (cp_parser_lookup_name): Don't look in dependent object_type. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/lambda-generic10.C: New test.
